Abstract: A fast silicon-on-insulator (SOI) waveguide-based optical device enhanced with minority charge carrier lifetime modifiers enables faster modulation speeds in optical attenuators, optical intensity/phase-modulators, and optical switches whose operation principles are based on free-carrier injection into a waveguide. The waveguide is doped with gold (Au) or platinum (Pt) such that when a drive voltage (applied to the device) is turned off, the minority charge carriers rapidly annihilate because gold doping reduces the minority carrier lifetime, which improves transient characteristics of the optical device. Integration of the fast active device with passive devices such as WDM demultiplexers/multiplexers on the SOI optical waveguide platform enables realization of monolithic integrated optical components for advanced functionality such as dynamic spectral equalization.

Abstract: A cost effective method is provided for assembly of hybrid optoelectronic circuits requiring flip-chip bonding of multiple active optoelectronic devices onto common substrate or optical bench platform with fine pitch and high accuracy “after-bonding” alignment to the alignment features on substrate and/or to other elements of the hybrid circuit. A Flip-Chip Bonder equipped with high precision Bonding Arm and optical and mechanical system, heated substrate chuck and heated pick-up tool may be used both for alignment and thermal bonding of active component dies to corresponding bonding pads on the common substrate using gold-tin (Au—Sn) solder disposed between die bonding pad and the corresponding substrate bonding pad.
